Cardiac arrhythmias and heart diseases can result in a limited performance capacity which could lead to anxiety and depression. Objective: The aim of this study was to investigate the prevalence of symptoms of depression among patients with cardiac arrhythmias. The intention was also to explore differences between men and women in the occurrence of symptoms of depression. Furthermore, the prevalence of symptoms of depression among patients with cardiac arrhythmias was compared with a Swedish general population. Method: For two weeks MADRS-S, a self-rating scale for depression, were distributed at a medicine ward where patients with cardiac arrhythmias are treated, at a hospital in Sweden.

The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.

With the purpose of finding the motives behind use, production and reuse of Open Educational Resources (OER), the writer has conducted a qualitative survey. The three main questions in this two years master?s thesis are:? Why do people use others? unmodified OER?? Why do people produce OER?? Why do people alter and reuse OER?The theoretic framework is built around Manuel Castells? network society, with its social and efficiency seeking dimension, along with the Knowledge commons. Some pedagogy is included as well.A web survey was distributed to 796 users of the Connexions OER repository. 95 responses were received.

The aim of this study is to examine the knowledge and experience of the bad breath among high school students in Kristianstad. A further objective was to measure the amount of VSC (Volatile Sulfur Compounds) among those who perceive themselves to have a bad breath. A questionnaire with 21 closed questions was distributed to 120 high school students from Kristianstad municipality who were between the ages of 17-20. The results of this study revealed that most of the students had good knowledge of halitosis. The majority of all participants thought it was important to smell fresh in the mouth and also experienced most of their breath as very good or good.

Arlanda airport is Sweden?s largest airport. The demand for comfort cooling of the airport?s buildings is high and is mainly provided by district cooling. District cooling is based on the same principle as district heating.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.

The purpose of this thesis is to investigate reading habits among parents of preschool children who do not use the public library. Another aim has been to investigate why these parents don?t use the library and if there is anything the library can do to change this. Little research had earlier been done on this subject. The theoretical framework consists of two different models.

This master?s thesis aims to analyze the ongoing debate in Scandinavia on research evaluation of the humanities. This field of research uses bibliometrics, quantative analysis of bibliographical units as a research assessment tool. In recent years evaluative bibliometrics has been an increasingly used method. In Scandinavia, governments have introduced new funding models for research in higher educational institutions.

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

The purpose of this survey was to map out the health pf some of the 11 and 12 years old children in the city of Umeå, as well as to find out what factors intend to influense the children´s health. A questionnaire was distributed in four 6th grade classes whitin the municipality of Umeå. Two of the schools were located in the city while two were located in near villages. This selection was decided in order to map out diffrences in health related to the children´s home environment. 80 pupils took part of this study.

This essay is about dogs that visit is used, whitin care of elderly. The dogs found caretakers once a week and one hour at a time. The focus has been placed on the dogs that go to the municipality's special accommodation and the research was done in a medium-sized municipality in Sweden. The focus of the narrowing of the work was done to the work situation for care staff to assess the impact of the visits the dogs presence. It was distributed questionnaires answered by care staff in which it concluded their visit to the dog's presence felt and how it impacted the situation.

Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.
